FLT

Filter arguments specify which tests to apply (test $i$ being defined in bank FLTR $i$). If multiple arguments are given then the logical AND of individual tests form the overall test. If an OR operation is required, it should be constructed explicitly:

   call flt(1)
   if_ok goto good_event
   call flt(5)
   if_ok goto good_event
   call flt(10,11,12)
   if_ok goto good_event
